A series of tertiary and secondary phosphine-B(C6F5)3 adducts are shown to undergo facile, thermal-induced rearrangement to give zwitterionic species of the form R3P(C6F4)BF(C6F5)2 and R2PH(C6F4)BF(C6F 5)2, respectively.

A series of classical B(C(6)F(5))(3)-phosphine adducts are shown to be reactive molecules. Reaction of (THF)B(C(6)F(5))(3) with phosphines are shown to effect ring-opening of THF affording the zwitterionic phosphonium-borate species of the form R(2)PH(C(4)H(8)O)B(C(6)F(5))(3) and R(3)P(C(4)H(8)O)B(C(6)F(5))(3). Alternatively, treatment of (THF)B(C(6)F(5))(3) with a lithium phosphide (R(2)PLi, R = tBu

A third strategy for formation of a metal complex of anionic phosphine-borate derivatives was demonstrated in the reaction of (COD)PtMe2 with the neutral phosphine-borane Mes2PC6F4B(C6F5)2 affording (COD)PtMe(Mes2PC6F4BMe(C6F5)2) 11. Extension of this reactivity to tBu2PH(CH2)4OB(C6F5)3) was demonstrated in the reaction with
